Answer:
x = 4
a = 79
b = 101
Step-by-step explanation:
Supplementary means equal to 180° after all angles are added together.
a=19x+3
b= 21x +17
(19x+3) + (21x +17) = 180
19x + 3 + 21x + 17 = 180
40x + 20 = 180
40x = 160
x = 4
a = 19(4)+3 = 79
b = 21(4) +17 = 101

If Art weighs 200 pounds at sea level, how much will he weigh on Mt. Everest, which is 29,035 feet above sea level? _ pounds
(Round answer to three decimal places. Do not round the numbers in your work. Only round the final answer)
If an object weighs m pounds at sea level, then its weight W (in pounds) at a height of h miles above sea level is given by W(h) = m(4000/(4000 + h))2. (1 mile = 5280 feet)
(W of h equals m times the quantity of (4000 over the quantity (4000 plus h)) squared)
If Art weighs 200 pounds at sea level, how much will he weigh on Mt. Everest, which is 29,035 feet above sea level?
Answer:
its 1,456,000
Step-by-step explanation:
first you multiply 200 times 5280 and add 4000 if thats right uon

Frank liked to buy packs of baseball cards. On 3 different days, he bought 3 packs. On 3 other days, he bought 4 packs each day. After that he split his packs with his 2 brothers. How many packs will they each have? Choose the expression that best matches this situation. [(3 x 3) + (4 x 3)] ÷ 3 [(3 x 3) + (4 x 3)] - 3 (3 x 3) + [(4 x 3) ÷ 3] [(3 x 3) + (4 x 3) ÷ 3]
Answer:
[(3 x 3) + (4 x 3)] ÷ 3
Step-by-step explanation:
Choose the expression that best matches this situation.
[(3 x 3) + (4 x 3)] ÷ 3
[(3 x 3) + (4 x 3)] - 3
(3 x 3) + [(4 x 3) ÷ 3]
[(3 x 3) + (4 x 3) ÷ 3]
On 3 different days, he bought 3 packs
= 3 × 3
= 9 packs
On 3 other days, he bought 4 packs each day.
= 4 × 3
= 12 packs
After that he split his packs with his 2 brothers
= (9 + 12) / 3
= 21 / 3
= 7 packs each for him and his two brothers
Here is the expression:
[(3 x 3) + (4 x 3)] ÷ 3
= (9 + 12) ÷ 3
= 21 / 3
= 7 packs

A gardener has ten plants (four tomato, two pepper, and four cucumber) to put in her garden. If she chooses the plants at random, what is the probability that the first one is a tomato plant, and the second one is a cucumber plant?
Answer:
8/45
Step-by-step explanation:
Given that:
Total Number of plants = 10
Number of tomato = 4
Number of pepper = 2
Number of cucumber = 4
If two plants are chosen at random:
Assume it is picked without replacement :
P(first is tomato plant) :
Recall : probability (p) = required outcome / Total possible outcomes
P(first is tomato plant) = 4 / 10 = 2/5
P(second is a cucumber plant) :
Number of plants = (10 - 1) =9 after first pick
P(second is a cucumber plant) = 4 / 9
Hence,
P(first tomato and second cucumber) = 2/5 * 4/9 (independent events)
2/5 * 4/9 = 8/45

What are the solution(s) of x2-4-0?
X=-4 or X-4
X=-2 or X= 2
X=2
X=4
Answer:
X = - 2 or X = 2
Step-by-step explanation:
*completing the square*
X^2 - 4 = 0
X^2 = 4
X = +-√4
x = +-2
x= -2, 2
*factoring*
X^2 - 4 = 0
(x-2)(x+2) = 0
|. |
x = 2, x = -2
________________________________
(x-2)(x+2) = x(x+2) - 2(x+2) = x^2 + 2x - 2x - 4 = x^2-4

Answer:
x= -29
Step-by-step explanation:
hi! let's start off by distributing.
4x+2(x+7)=5(x-3)
4x+(2x+14)=5x-15 combine like terms
6x+14=5x-15 subtract 5x on both sides
x+14=-15 subtract 14 on both sides
x= -29
there's your answer!
Answer:
x = -29
Step-by-step explanation:
4x + 2x +14 = 5x - 15
6x + 14 =5x - 15
x = -29

can someone tell me how to solve translations please?
Step-by-step explanation:
Hey there!
Here; The coordinates are ; H(-4,-2), G(-5,3), F(-2,1)
The translation P(x,y) = P'(X+7,y)
Use same formula.
H(-4,-2) -------> P'(3,-2)
G(-5,3)-----------> G'(2,3)
F(-2,1)------------> F'(5,1)
Therefore, the answer is Option C.
Hope it helps..
